The Mets have sent cash, John Buck and Marlon Byrd to the Pirates for 19-year-old Single-A second baseman Dilson Herrera and a player to be named later, the team announced.

Matt den Dekker, Anthony Recker and Robert Carson are expected to be in uniform and available for tonight’s game, ESPN New York reported earlier today.

Herrera is playing his first full season in Single-A, where he is batting .265 with a .330 OBP. He’s hit 27 doubles in 109 games, with 11 home run and 11 stolen bases. He was ranked as the 11th-best prospect in Pittsburgh’s farm system entering 2013 by MLB.com, and the ninth-best second base prospect in baseball (one slot behind Wilmer Flores).

“While he’s not the biggest guy in the world, he’s shown he can really hit and projects to be an above-average hitter in the future, with more power than you’d expect from a guy his size,” Mayo said in his report. Herrera is a an above-average runner, who should be able steal bases consistently.

Herrera was the second-youngest player ever to be selected for the MLB Futures Game, which he played in this summer in Citi Field.
